CARRIER FOR e'oNv'EYlNG GLASS FROM FLATT'ING-OV'ENS.

sPEcIFIcATIoIv formingpa'rt of Letters Patent No. 474,983', ateaivray 17,1892; Application fu'ea'necemter 22,1891. serial No. 415,858. et@ :Hoden B e it known that I, THEODOR A. ZELLERS, of Ottatva, `in thecounty of La Salle and State of Illinois, have invented certain new and useful Improvements in Carriers for Conveying Glass from Flatting-Ovens; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letio ters of reference marked thereon, which form a part of this specification.

This invention relates to devices for conveying sheets of glass from the table of a flatting-oven through the annealing-tunnel.

I5 It has for its object to provide a construction whereby a continuous motion is given to the ilattened plates through the tunnel and in which the different portions of the carrier are of less temperature the farther they are zo from the atting-oven, corresponding, therefore, with the diminishing temperature of the receding glass plates which it carries.

To this end the invention consists, essentially, in a series of short endless metallic z5 chain-carriers severally composed of a plurality of chains arranged side by side and as complete sections arranged endv to end to form the complete carrying device.

Heretofore an entire carrier composed of a 3o number of endlesschain belts arranged side by side and of the full length of 4the carrier has been tried and found unsuitable for the purpose. In that case, because each chain extended the entire length of the carrier and passed from the interior of the oven to the outer vextremity of the tunnel, all portions of Veach of the chains were successively subjected to the high heat of the oven and the loW heat at the outer end of the tunnel.

4o Was that they were not hot enough When Within the oven and were too hot when at the opposite extremity of the tunnel.`y The effect upon the glass Was of course to frequently break it by reason of the Wide differences in temperature between the plates and the carr1er.

By my improvement the advantages of the endless-chain carrier are fully secured and the objections attendant upon the carrier con- 5o stituted of the continuous belts referred to are obviated.

The result Referring to theI accompanying'dratvings, which illustrate an application' of my Inven- `tion to a flatting-oven and tunnel, Figure 1 t is a horizontal section ofa flatting-oven and its connected tunnel in a planev above the carrier. Fig. 2 isa vertical section through the oven and adjacent portion of the tunnel in line 2 2 of Fig. 1. Fig. 3 isa'vertical section in the same lineof the outer extremity of the 6o tunnel. Fig. 4 is an external side view of the outer portion of the tunnel. Fig. 5 is an enlarged side elevation of a section of the endless-chain-belt carrier. Fig. 6 is a detail plan view of a portion of the samej 65 A represents a flatting-oven, B a revolving flatting table therein, and C a tunnel leading from the oven. Within this tunnel is arranged an endless-chain-belt carr1er D, of which d d d2, &c., are the sections. Each 7o of the sections of the carrier D is composed of a series of relatively short endless chain belts ee, trained over Sprocket-pulleys e upon transverse shafts e2. The shafts e2 at the extremities of the entire carrier have only one series of sprocket-pulleys e; but all the intervening shafts are, as shown and as prefererably constructed, provided with double the number of sprocket-pulleys, so that the endless belts of adjacent sections connect with 8o each other through common pulley-shafts and the chains of adjacent sections interlap With each other and give a continuous and uniform moving surface to the carrier as a Whole. In this construction power may be applied to any one of the shafts e2, as indicated, by a crank on the shaft at the outer extremity of the carrier. As a means of supporting the sprocket-carrying shafts, which are of course arranged 9o transversely to the tunnel C,`I prefer to provide holes or passages c c through the Walls of the tunnel and journal-boxes c' for the shafts exterior to the latter for all ends of shafts not within the oven. The inner extremities of the shaft or shafts which are Within the oven may have their journal-bearings supported in any suit-able manner, the illustration given in Fig. l Showing said bearings to be upheld upon an iron beam c2, rest- Ioo ing at its outer end in the masonry and at its inner end upon a projecting beam c3, supported and protruding from the junction of the adjacent interior arches. As a desirable construction for the support Ofthe journalbearings which are external to the tunnel- Walls, I prefer to employ Wooden beams or stringers F, resting upon and fastened to ledges formed on the outer surfaces of the tunnel-Walls, the journal-boxes being bolted to these stringers.

The details Of construction .may be Inodi fied according to circumstances or to the preferences of the builder. The essential feature of the invention is the chain-belt carrier made Y of relatively short sections arranged end to glass from the oven through the tunnel, c omposed of a series of relatively short sections placed endV to end and consisting each of a transverse series of endless belts, substantially as described.

2. In combination With a flatting-oven and tunnel, a carrier composed of sections severally made up of atransverse series of endless belts and transverse pulley-shafts, of which the intermediate shafts carry the pulleys for the two adjacent sections.

3. In combination With the tunnel leading from a latting-Oven and a belt-carrier Within the tunnel, composed of short endless belts arranged end to end, shafts for the carrier,

-Which project through the side Walls Of the tunnel, and j Ournal-bearings for said shaft eX- terior to said side Walls.

In testimony that I claim the foregoing as my invention I aflix my signature in presence of two witnesses.
